From 2026.3.15 until 2026.6.4, mise loads github.credential_command from local project config before any trust decision, then executes that value with sh -c when resolving a GitHub token. An attacker who can place a .mise.toml in a repository can execute arbitrary shell commands when the victim runs a GitHub-related mise command and no higher-priority GitHub token environment variable is set. This vulnerability is fixed in 2026.6.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","score":6.3},"cwes":["CWE-78"],"references":["https://github.com/jdx/mise/security/advisories/GHSA-29hf-rm4x-xxph","https://github.com/jdx/mise/security/advisories/GHSA-29hf-rm4x-xxph"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-55448","score":0.00158,"percentile":0.04916,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-29hf-rm4x-xxph","url":"https://osv.dev/vulnerability/GHSA-29hf-rm4x-xxph","summary":"Mise's local credential_command executes untrusted config","modified":"2026-06-23T18:41:30.576100Z","packages":[{"ecosystem":"crates.io","name":"mise","purl":"pkg:cargo/mise","ranges":[">=2026.3.15 <2026.6.4"],"fixed":["2026.6.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
